I v/r
Ohms law
I have measured 100ma through circuit using ammeter getting 100ma but my math keeps coming up with it= 338ma
This is a parallel circuit with
12.70v battery
Connecting 14 LEDs total
4 resistors each 150ohm
4 strings of LEDs running series-parallel
S1= 2.2x4 LEDs / 150ohm
S2= 2.2x4 LEDs /150ohm
S3= 3.2x3 LEDs / 150ohm
S4= 3.2x3 LEDs /150ohm
My math says 37.5ohms for R-req
338ma
Somethings not right please help
